The synthesis of 1‐vinyl‐, 3‐vinyl‐ and 3‐alkynylcyclobutenes has been achieved by a gold(I)‐catalyzed [2+2] cycloaddition reaction. One‐pot transformations of the versatile cyclobutenes render cyclopentenes, 2,3‐dihydrofurans, polycyclic skeletons and beyond.
1-乙烯基,3-乙烯基和3-炔基环丁烯的合成已通过金(I)催化的[2 + 2]环加成反应完成。通用环丁烯的一锅转换可生成环戊烯,2,3-二氢呋喃,多环骨架等。
